HPB400 Wire Rod is a Chinese national standard hot-rolled low-carbon steel wire rod with a specified yield strength of 400MPa, a high-strength variant of construction wire rod superior to ordinary low-grade wire rods. It retains excellent plasticity, ductility and cold workability, easy to straighten, draw and bend for on-site processing, and features good weldability for diverse fabrication needs. Available in full standard coil specifications with stable mechanical properties and uniform material quality, it’s a cost-effective mainstream raw material for construction steel processing and light metal fabrication.
